Louis is ecstatic to finally introduce his childhood best friend, Y/n, to the boys. But before bringing her in, he lays down a condition - they are not to hit on her, especially Harry. Louis gives Harry a sly look, "We all know you have a way with the ladies, mate. I don't want things to get awkward." Harry scoffs, "I'm not going to make a move on your best friend, Louis. I swear it." However, when Y/n walks in an hour later, Harry is blown away by her looks. He didn't expect her to be so stunning. As Louis introduces her to Niall, Harry is drawn to her like a moth to a flame. Y/n catches his eye and gives him a warm smile, and Harry knows he's in trouble. Despite his promise, he can't resist the temptation to pursue her.
